CONTINUOUS AUTOCLAVE FOR METAL OXIDIZING LEACHING Russian patent published in 2001 - IPC

Abstract RU 2171709 C1

FIELD: equipment for hydrometallurgy, particularly, designs of continuous autoclaves for oxidizing leaching of ores and concentrates at high temperatures and pressures. SUBSTANCE: autoclave has device for introduction of initial concentrate pulp; horizontal cylindrical body; device for supply of gaseous oxidizer in form of jets and located along the entire length of body and/or combined with device for pulp introduction; heating elements located over body outer surface; circular filter for separation of solution with useful components; device for discharge of depleted pulp. Diameter of body hole for introduction in initial concentrate pulp is larger than that of hole for discharge of depleted pulp. EFFECT: simplified design of autoclave, reduce maintenance costs and higher efficiency of metal recovery. 4 cl, 1 dwg
